Documentation

Use Telegraf to write CSV data

InfluxDB 3 Enterprise is in Public Alpha

InfluxDB 3 Enterprise is in public alpha and available for testing and feedback, but is not meant for production use. Both the product and this documentation are works in progress. We welcome and encourage your input about your experience with the alpha and invite you to join our public channels for updates and to share feedback.

Alpha expectations and recommendations

Use the Telegraf file input plugin to read and parse CSV data into line protocol and write it to InfluxDB 3 Enterprise. Telegraf is a plugin-based agent that collects metrics from different sources and writes them to specified destinations.

Configure Telegraf to read CSV files

  1. Add and enable the inputs.file plugin in your Telegraf configuration file.
  2. Use the files option to specify the list of CSV files to read. CSV files must be accessible by the Telegraf agent.
  3. Set the data_format option to csv.
  4. Define all other csv_ configuration options specific to the CSV data you want to write to InfluxDB 3 Enterprise. For detailed information about each of the CSV format configuration options, see CSV input data format.
[[inputs.file]]
  files = ["/path/to/example.csv"]
  data_format = "csv"
  csv_header_row_count = 0
  csv_column_names = []
  csv_column_types = []
  csv_skip_rows = 0
  csv_metadata_rows = 0
  csv_metadata_separators = [":", "="]
  csv_metadata_trim_set = ""
  csv_skip_columns = 0
  csv_delimiter = ","
  csv_comment = ""
  csv_trim_space = false
  csv_tag_columns = []
  csv_measurement_column = ""
  csv_timestamp_column = ""
  csv_timestamp_format = ""
  csv_timezone = ""
  csv_skip_values = []
  csv_skip_errors = false
  csv_reset_mode = "none"

Configure Telegraf to write to InfluxDB

To send data to InfluxDB 3 Enterprise, enable and configure the influxdb_v2 output plugin in your telegraf.conf.

[[inputs.file]]
  files = ["/path/to/example.csv"]
  data_format = "csv"
  csv_header_row_count = 0
  csv_column_names = []
  csv_column_types = []
  csv_skip_rows = 0
  csv_metadata_rows = 0
  csv_metadata_separators = [":", "="]
  csv_metadata_trim_set = ""
  csv_skip_columns = 0
  csv_delimiter = ","
  csv_comment = ""
  csv_trim_space = false
  csv_tag_columns = []
  csv_measurement_column = ""
  csv_timestamp_column = ""
  csv_timestamp_format = ""
  csv_timezone = ""
  csv_skip_values = []
  csv_skip_errors = false
  csv_reset_mode = "none"

[[outputs.influxdb_v2]]
  urls = ["http://localhost:8181"]
  token = "
AUTH_TOKEN
"
organization = "" bucket = "
DATABASE_NAME
"
content_encoding = "gzip"

Replace the following:

  • DATABASE_NAME: the name of the database to write data to

  • AUTH_TOKEN: your InfluxDB 3 Enterprise authorization token. Store this in a secret store or environment variable to avoid exposing the raw token string.

    While in alpha, InfluxDB 3 Enterprise does not require an authorization token. For the token option, provide an arbitrary, non-empty token string.

    Store your authorization token as an environment variable

    Avoid storing a plain text token in your Telegraf configuration file. Store the token as an environment variable and then reference the environment variable in your configuration file using string interpolation. For example:

    [[outputs.influxdb_v2]]
      urls = ["http://localhost:8181"]
      token = "${INFLUX_TOKEN}"
      # ...
    

Restart the Telegraf agent to apply the configuration change and write the CSV data to InfluxDB 3 Enterprise.

Other Telegraf configuration options

The preceding examples describe Telegraf configurations necessary for writing to InfluxDB 3 Enterprise. The influxdb_v2 output plugin provides several other configuration options. For more information, see the influxdb_v2 plugin options on GitHub.

InfluxDB 3 Open Source Now in Public Alpha

InfluxDB 3 Open Source is now available for alpha testing, licensed under MIT or Apache 2 licensing.

We are releasing two products as part of the alpha.

InfluxDB 3 Core, is our new open source product. It is a recent-data engine for time series and event data. InfluxDB 3 Enterprise is a commercial version that builds on Core’s foundation, adding historical query capability, read replicas, high availability, scalability, and fine-grained security.
